sql server clustering : slow work of SQL server

Hello!

Month ago we installed the did cluster for Microsoft server.

It is 3 machines under Windows Server 2003 Enterprise.

1 and 2 are cluster with MS SQL Server 2000 + SP3

3 is the storage under WinTarget 1.2 for database only.

web server is on the machine #4 under Windows 2000.

so sometimes (once per day) the database starting to work really slow.

(i can connect some pages on the website, but when i'm trying to open pages
that consist data i'm waiting for a really long time (10 - 12 min) or
getting timeout error. All query are very simple.

Usually i'm fixing it by

1. restarting the MS SQL service and then

2. bring online cluster group from cluster administrator console.

What it is can be? Where to search the reason and how to fix?

Thank you

Serdge

Hi

Check that you don't have any blocking in the DB. run sp_who2 when the
problem occurs.

Are you using a non fiber SCSI or non iSCSI storage device? Is server 3
storage? If so, that is a NAS and may not be supported.

Regards
Mike

When problem occurs... the sqlserver process have about 1Gb memory.
After restarting it take just 70k memory and working fine...
Seems to me it is kind of memory leak...
Any ideas and how to fight?
